Abstract: ABSTRACT OF THE DISCLOSURE A knife sharpener is disposed adjacent a second electrical appliance of a design family.  In an inoperative position, the knife sharpener includes design features mimicking the remainder of the design family.  When moved to an operative position, the knife sharpener makes its sharpening wheel accessible to the edges of a knife blade.  An energizing switch is coordinated for actuation as the knife sharpener reaches its operational position.  In a combination that uses the same electric motor to drive the knife sharpener and a second appliance, different motor speeds are produced appropriate for the two functions to be performed.  A bi-directional spring loading assembly permits deflection of the sharpening wheel in opposed lateral directions from a positively controlled neutral position to maintain substantially uniform application of sharpening force on the knife edges.  An articulating knife guide permits the use of a single guide slot which can be inclined on either size of the sharpening wheel.  An integral detent spring ensures that the guide slot may remain in only permitted inclinations.

Abstract: Abstract Process for production of potentiometers having a cup shaped casing holding a part circular resistance element provided with terminals, a slider holder, a slider contacting the resistance element and a circular collector provided with a terminal superimposed on and contacting the slider and closing the casing.   Such potentiometers may be formed by forming a subassembly including the casing, the resistance element and its terminals in the form of a continuous band, forming a second subassembly including the slider holder, slider and collector also on a continuous band, and coupling the two bands.  In this invention, the first subassembly is formed by die cutting a continuous laminar band of conductive material to form two rows of parallel terminals oriented perpendicular to the direction of the length of the band, joined by cross strips, directly facing and longitudinally staggered relative to one another and extending inwardly from opposite sides of the band, each side of which is provided with holes also longitudinally staggered relative to the holes on the opposite side, and the terminals are coupled to the resistance element by stapling it within the bottom of the casing by bending appendages formed on the terminals.

Title: Effervescent tablet containing a salicylic acid-forming agent
Inventor: STEPHAN GUENTER
IPC: A61K9/46
Filed: 1989-09-14
Granted: 1997-09-16
Abstract: It is known to produce effervescent tablets incorporating salicyl acid analgetics gained synthetically, and, if required, vitamin adjuvants.  In order to avoid the disadvantages of synthetically manufactured salicyl acid in such effervescent tablets, namely the irritation of the gastric mucosas and the inhibition of thrombocyte aggregation, and simultaneously to bring about new fields of use for effervescent tablets, an effervescent tablet is suggested which has, as an analgesic agent forming salicylic acid, a water-soluble plant extract of the salicis extract type (willow bark extract) with a high active substance content.  Thus, a galenically appropriate administration form of these generally extremely hygroscopic extracts is obtained.  In the effervescent tablet, high active substance quantities can be resorbed rapidly, the salicyl acid forming the final active substance only being formed in the liver.

Abstract: The invention concerns a method and a device for removing water out of the perforations in a suction roll, in which method a doctor blade (11) is brought into contact with the face (T1 min ) of the suction roll (T). The doctor blade (11) is mounted with its slat face (C) in such an angular position in relation to the face (T1 min ) of the suction roll (T1) that the angle between the face plane (C) of the doctor blade and the tangential direction of the face of the suction roll, when the tangent is drawn at the contact point between the tip of the doctor blade and the face of the suction roll, is within a range of 2... 10 DEG . In the method, water is removed by means of the inletside surface plane (D) of the doctor blade, the inlet side being seen in the sense of rotation of the suction roll, and the water is allowed to flow smoothly over the doctor blade out of contact with the construction. In the method, according to the invention, water is removed additionally by means of a suction effect out of the area (V) between the slat face (C) of the doctor blade and the suction roll, negative pressure being produced in said space (V). The negative pressure produces flow of water out of the perforations or grooves (F) in the suction roll. <IMAGE>

Date Jan. 25, 1996The invention relates to a method for warming up a spare process in parallel with an active process in a replicated real-time switching system, in particular in a telephone exchange. The switching system comprises an active control unit (WP) having, permanently or when necessary, a replicating hot-standby spare unit (SP) connected to a common internal message bus, so that the spare unit performs the same processes as the active control unit in parallel. In accordance with the invention, the operation of the active process ( sigma WO) to be replicated is temporarily frozen in the active control unit (WP) when the process has no tasks to be performed, the other processes of the active control unit simultaneously being kept in operation. After this a spare process ( sigma SP) is created to the spare unit (SP), and the state data ( sigma WO) of the active process is loaded into the spare process. Provided that no new tasks have come in during this time to the active process ( sigma WO), the warm-up is found successful. The warm-up is found failed if new tasks have come in.

Abstract: An encryption key, required to encrypt and decrypt data according to a predefined algorithm, is usually retained in a volatile memory device. Detection of loss of the key or corruption of the key is freqeuntly possible only by means of the encryption circuit itself testing the key. Automated and repetitive testing of encryption keys by means of a processor or a control circuit periodically requesting the encryption circuit to test an encryption key minimizes data loss and system down time due to corrupted or lost keys.

Granted: 2000-02-08
Abstract: An apparatus for controlling the tilt angle of a doctor blade includes two support blocks of a doctor blade supporting beam, a first actuator by which the supports are movable about on their bearing points, a blade supporting beam pivotally mounted between upper parts of the support blocks having a doctor blade attached to the beam, and a second actuator by which the blade supporting beam is movable about on its pivoting point in order to control the tilt angle and loading of the blade.      Between the support blocks, an axle is pivotally mounted which is arranged via a transfer apparatus to rotate essentially in the same way as the blade support beam. At least one guiding member is eccentrically attached to the axle. The first actuator is arranged to rest against the guiding member, whereby the eccentricity of the guiding member causes the rotation of the supporting blocks about the bearing points, when the blade supporting beam is rotated around the bearing point with the help of the second actuator whereby it is possible to maintain a constant tip angle during any changes in the blade loading.
